I have worked with my fair share of datasheets under NDA so I understand that you can't share it but thanks a lot for making the effort to verify whether it would be possible.
Meanwhile I have found some alternatives which would allow me to reduce fpga resources but that would require me to preprocess the data on CPU before it's being sent to the CFE. From what I've been able to gather from the docs it seems that it could be possible. The idea would be to let the fpga write a custom format and have the pi write it to memory after which I process the data and use the memory-to-CFE pipeline to process the image on tghe rp1-cfe. For this to work the pi would need to write the raw data unmodified to memory.
Do I need to have the pi believe that the incoming data is single channel 16 bit data and disable pisp data compression to do that, or can I just set up the mediacontroller to output to /dev/video0 and use v4l controls to capture the raw unmodified datastream?
I went through the Raspberry Pi Image Signal Processor(PiSP) Specification and it look like once I have the data, I could use libpisp to process e.g. 10 bit smia packed (4pixels per 5 bytes) data, or am I missing something?
